The typical mattress is designed to be a flat surface that is equally supportive in all areas – since your body has curves & joints (not perfectly flat surfaces), this type of mattress applies too much pressure in certain areas causing hot spots & joint pain in the morning.

Other mattresses are designed to completely contour to your body, providing not enough support, forcing your muscles to work for a healthy posture while you sleep.

How can I tell? Stretch in the morning for 15 minutes. If your aches & pains go away, then you can probably blame your mattress.

Back sleepers – If you like sleeping on your back, but your mattress is too firm or has begun to form a valley, you’ll feel like your back is attacking you, too soft and you’ll feel like you’re sinking in quicksand.

Side & stomach sleepers – A mattress that is too firm will certainly lead to problems since your joints naturally would like to sink slightly into the cushion of your mattress. A mattress that is too soft will lead to spine issues over time and expensive chiropractic bills.
